                        path of the own package, as required for
                        executing binary programs delivered with it.

cpp_dist_tom            Function to calcutate distance
cpp_filter_base         Initialise boosting with chosen accelerator
                        hardware (x86, AVX, FMA)
cpp_filter_end          Boosting cleanup (required to free memory)
cpp_filter_step         Single boosting step
cpp_tree_search         Tree search.
cut_dendro              Module detection for an individual tree
cut_trees               Module detection for the results from a
                        nb_mcupgma call
mcupgma_exec            Execute a program/script from the installed
                        MCUPGMA suite.
nb_clust                Netboost clustering step
nb_dist                 Calculate distance (external wrapper for
                        internal C++ function) Parallelisation inside
                        C++ program with RcppParallel.
nb_filter               Boosting via C++ function. Parallelisation by
                        R-package parallel with forking (overhead of
                        this method does not fall into account as
                        single steps are ~10s).
nb_mcupgma              Calculate dendrogram for a sparse distance
                        matrix (external wrapper MC-UPGMA clustering
                        package Loewenstein et al.
nb_moduleEigengenes     Netboost module aggregate extraction.
nb_plot_dendro          Plot dendrogram from Netboost output.
nb_summary              Summarize results from a forest. Plot trees
                        together.
nb_tranfer              Transfer of Netboost clustering to new data.
netboost                Netboost clustering.
netboostMCUPGMAPath     Returns the absolute path to folder with
                        mcupgma executables and scripts.
netboostPackagePath     Returns the absolute path to "exec" folder in
                        the package.
netboostTmpCleanup      Cleans the netboost temporary folder. This can
                        be useful during the session as mcupgma creates
                        vast directory structures (for iterations).
                        Creates the own folder (all netboost temporary
                        data is stored in netboostTmpPath(), which is
                        equal to tempdir()/netboost). Also used for
                        first time setup of folder.
netboostTmpPath         Returns the absolute path to temporary folder
                        of the package. To change temporary path, use
                        normal R variables (TEMPDIR etc).
tcga_aml_meth_rna_chr18
                        TCGA RNA and methylation measurement on a
                        subset of chromosome 18 for 80 AML patients.
tree_dendro             Calculate the dendrogram for an individual tree
tree_search             Extracts independent trees from nb_mcupgma
                        results (external wrapper for internal C++
                        function)
